The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.

crypto_aead_blocksize – obtain block size of cipher Synopsis unsigned int crypto_aead_blocksize(struct crypto_aead *tfm); Arguments tfm cipher handle Description The block size for the AEAD referenced with the cipher handle is returned. The caller may use that information to allocate appropriate memory for the data returned by the encryption or decryption operation Return block size of…
crypto_aead_authsize – obtain maximum authentication data size Synopsis unsigned int crypto_aead_authsize(struct crypto_aead *tfm); Arguments tfm cipher handle Description The maximum size of the authentication data for the AEAD cipher referenced by the AEAD cipher handle is returned. The authentication data size may be zero if the cipher implements a hard-coded maximum. The authentication data may…
crypto_ablkcipher_setkey – set key for cipher Synopsis int crypto_ablkcipher_setkey(struct crypto_ablkcipher *tfm, const u8 *key, unsigned int keylen); Arguments tfm cipher handle key buffer holding the key keylen length of the key in bytes Description The caller provided key is set for the ablkcipher referenced by the cipher handle. Note, the key length determines the cipher…
